  Q: How to remove the intake manifold on Toyota Venza?

  A:

  Discharging fuel system pressure stands as the first step when removing the intake manifold. Users need to disconnect the negative battery cable followed by a potential system initialization procedure after reconnecting the cable. You should begin by taking off the Throttle Body assembly after disconnecting the vacuum switching valve assembly for ACIS and removing its two vacuum hoses, two union to connector tube hoses, clamp and connector before removing the bolt. Remove the No. 2 ventilation hose from the intake manifold then disconnect its union to connector tube hose. The next step requires removal of the fuel delivery pipe sub-assembly. The intake manifold removal process involves removing two bolts along with two wire harness brackets and disconnecting the fuel vapor feed hose and its clamp and connector and extracting the bolt combined with a wire harness bracket. The procedure takes between 1 and 3 seconds to apply battery voltage to the connector terminals while closing tumble control valves. The technique must not surpass 3 seconds because it could damage the actuator. Proceed to remove the bolt while detaching both clamp mechanisms from the intake manifold along with bracket until the intake air control valve actuator connector disconnectes and all six bolts securing the intake manifold are removed. Tumble control valves can sustain damage when the intake manifold installation occurs without pre-closing them. Eliminate the intake manifold gasket while unplugging the two vacuum hoses situated at the intake manifold and extracting the check valve. The last step includes removing the bolt as well as the wiring harness clamp bracket after which you can take out the three bolts that secure the engine mounting damper.

  Q: How to install the intake manifold on Toyota Venza?

  A:

  Before mounting the intake manifold you must secure the engine mounting damper through 3 bolts which need to be torqued at 9.0 Nm (92 kgf-cm, 80 in-lbf). Attach the wiring harness clamp bracket to the manifold through a torqued bolt which amounts to 8.4 Nm (86 kgf-cm, 74 in-lbf). Fit the check valve into position through the 2 vacuum hoses attached to the intake manifold. The tumble control valves should be closed through terminal connection of the actuator to the battery to avoid installation damage. Place a new gasket on the intake manifold and fasten it through six bolts following a specific installation sequence while requiring 21 Nm torque (214 kgf-cm or 15 ft-lbf). Secure the intake air control actuator connector and tighten 2 clamps onto the intake manifold and bracket while installing the wire harness through a 8.4 Nm (86 kgf-cm, 74 in-lbf) torquing process. Experience follows by bolting and torquing another bracket assembly. Then link the fuel vapor feed hose through its clamp and connector before attaching the two wire harness brackets with 2 bolts at 8.4 Nm (86 kgf-cm, 74 in-lbf). The installation procedure begins with the sub-assembly followed by connecting the hose between the union and connector tube to the intake manifold. Finally, connect the ventilation hose at position number two. Replace the vacuum switching valve assembly (which has ACIS functionality) by tightening its bolt to 9.0 Nm (92 kgf-cm, 80 in-lbf) before installing its 2 vacuum hoses, 2 union to connector tube hoses and connector as well as clamp. Install the Throttle Body followed by connecting the cable to the negative battery terminal while system initialization requirements may arise after the reconnection process. Finally, inspect for fuel leaks.
